I believe it was a link error. It's been a few weeks. :) I can go and look, but also passing -pthread or -pthreads is fairly common "in the ecosystem" (across the random set of stuff I built). The -pthread flag implies something like -D_MT -lpthread. Informally, if you are talking about locks, you are talking about pthreads (or Windows), and the various -pthread / -pthreads switches make sense, or in any case, imho, on platforms that give it any meaning, are fairly harmless. Yeah, I know you might map an extra .so unnecessarily. - Jay ________________________________ From: Assaf Gordon <assafgor...@gmail.com> Sent: Wednesday, August 4, 2021 9:29 PM To: Jay K <jayk...@hotmail.com>; 49...@debbugs.gnu.org <49...@debbugs.gnu.org> Cc: Larkin Nickle <m...@larbob.org>; bug-gnulib@gnu.org List <bug-gnulib@gnu.org> Subject: Re: bug#49308: GNU sed for Tru6 configure CFLAGS?

To be more precise: Does the compiler complain that the "mbtowc_with_lock" function has an unresolved symbol relating to 'pthreads' ? or that the symbol "mbtowc_with_lock" is unresolved ? > > Perhaps configure.ac can/should do that automatically? > > Perhaps this can/should somehow be done more globally, beyond sed? > i.e. I should refer to autoconf mailing list? 'mbtowc_with_lock' comes from the gnulib module 'mbtowc-lock': https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgit.savannah.gnu.org%2Fcgit%2Fgnulib.git%2Ftree%2Flib%2Fmbtowc-lock.h&data=04%7C01%7C%7C9684e1475a5e409f239008d9578efdc9%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637637093914845575%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=Vxw5U%2B2Wo6O7OT%2FYoAlYcNNL4HXNVAfq1dhCPFa39OE%3D&reserved=0 I see the file has several #ifdefs for specific systems, perhaps Tru64 can be added? Gnulib experts can perhaps answer this better. (But as you're aware, there's a limited amount of support for older systems...) regards, - assaf
